sPEcIFIcATIo'Nf'frming part of Letters Patent No. 753,490, dated March1, 1904. Application iiled April 9, 1903. Serial No. 151,896. A(Nomodell) To a/ZZ whom t may con/cern:

Be it known that I, BRADBURY HILL, a citizen of the United States,residing at Osage, in the county of Mitchell and State of Iowa, haveinvented a new and useful Copy-Holder, of which the following is aspecification.

The invention relates to improvements in copy-holders.

The object of the presentinventionis to improve the construction ofcopy-holders and to provide a simple, inexpensive, and eiiicient devicedesigned to be applied to large books for enabling accurate copies andvextracts to be made from the same and adapted to conform to theconguration of and lie approximately fiat against a book-in which theleaves round up or bulge at the center.

A further object of the invention is to provide a device of thischaracter adapted to be readily adjusted to suit books of differentsizes and capable of enabling the indicator to be readily moved downwardor advanced on its support and of effectually preventing the same fromslipping accidentally, and thereby failing to indicate properly the partto be copied.

With these .and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges inthe form, proportions, size, and minor details of construc-`tion Within the scope of the claims may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the invention. A

In the drawings, Figure 1 is a perspective view of a copy-holderconstructed in accordance with this invention. Fig. 2 is a verticalsectional view of the same. Fig. 3 is a horizontal sectional view, theindicator-'arms being shown in plan view. Fig. 4L is a 'transversesectional view illustrating .the manner of mounting the indicator on thesupporting-rod.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings. I

l designates a rod forming a support for an adjustable indicator andprovided at its lower end with a resilient hook 2, forming a clampingdevice and adapted to engage the bottom of a book at the center thereof.The rod or support is secured to the top of a book by an adjustableclamping device, consisting of a bar 3, centrally connected with the rod1 and provided at its ends with rearwardlyprojecting hooks 4, adapted toengage several leaves of a book. The hooks 4t may be made of any desiredsize -to enable the requisite number Vof leaves tobe engaged, and thebar is provided with a centrally-arranged rearwardly-projectingresilient hook 5, adapted to engage the top of the book at the centerthereof. -In practice the lower hook of the rod is first engaged withthe bottom of a book, and the upper clamping device is then engaged withthe top of the book and pressed downward or inward to clasp the booktightly, and the upper clamping device is secured in its adjustment by aclamping-screw 6, mounted in a threaded perforation of a casing or guideV7, having an aperture for the rod, which is preferably round. VThe rodmay be constructed of metal or any other suitable material, and thelower resilient hook may be formed integral with the rod, as indicatedin Fig. 2 of the drawings, or it may be constructed in any other desiredmanner, as will be readily understood. The upper clamping device may beconstructed of metal or any other suitable material, and the central andend hooks may be applied to the bar, which forms the body portion of theupper clamping device, in any desired manner. The end hooks 4 arepreferably integral with the bar, and

the central hook may be either formed integral with the bar or beconstructed separatev therefrom, as desired. Any form of casing ,7 maybe employed to form a guide for the upper clamping device.

The indicator, which may be constructed lof any suitable material,preferably consists of `a central section 8 and end sections 9,connected with the terminals of 'the centralV section by hinges 10 topermit 'the arms formed I IOO I sections is located adjacent to thesupport and approximately at a point where a book is liable to bulge orround up in order to cause the outer section to hug closely the book.The former is provided at its outer end with a weight 11. Any form ofhinge joint or connection may be employed, and instead of providingseparate hinges, as illustrated in the accompanying drawings, the eyesmay be carried by the sections and be formed integral with the same.

The central section 8 of the indicator is provided with a casing 12,through which passes the rod 1, which forms a guide and which is engagedby a pair of spring-actuated clamping-levers 13, fulcrumed between theirends at the front of the casing 12 and provided with inner curved jaws14. for engaging the rod 1 at opposite sides thereof. The terminals ofthe jaws are connected by a coiled spring 15, which holds the jawsfirmly in engagement with the combined guide and supporting rod. Theouter portions of the levers are shaped to form handles and are adaptedto be compressed to distend the spring and open the jaws, to ypermit theindicator to slide freely on the rod. When the outer portions of theclamping-levers are released, the spring retracts and automaticallycarries the jaws into engagement with the rod, whereby the indicator isfirmly clamped to the rod and is efyfectually prevented fromaccidentally slipping thereon. rlhe inner ends of the levers areperforated to receive the terminals of the coiled 'spring 15; but thelatter may be connected with the levers in any other desired manner. Thelevers are preferably connected with the casing by a pivot 16, and theyextend outward through a slot 17. The casing is provided at oppositesides with laterally-extending perforated ears 18 for the reception offastening devices for securing the casing to the central section of theindicator; but the casing may be applied tothe said central section inany other desired manner.

I In order to enable the indicator to slide freely over the book towhich the device is applied, the central section is provided withopposite antifriction devices, preferably consisting of rollers 19,mounted in suitable slots or openings and projecting from the inner orrear' face of the said section. The antifriction-rollers may bejournaled on the central section in any suitable manner, and they enablethe indicator to slide easily over the surfaces of the opposite pages ofa book and prevent the indicator from binding or accidentally tearing orotherwise injuring the leaves. The present invention is designedespecially for use in connection with large books containing publicrecords and is adapted to be readily applied to books of differentsizes, and indicators having arms of different lengths may be employedand can be quickly applied vto the combined guide and supporting rod.

Also a single indicator-arm may be employed, if desired.

The weights at the outer ends of the outer sections of the indicatorprevent the ends of the latter from being lifted or moved away from thebook to which the device is applied by any bulging or rounding of thebook at the center. When the device is applied to books which arecapable of opening out perfectly fiat, the indicator may be providedwith a stif unyielding arm and the weights may be omitted. Also theindicator may be provided at each arm with a plurality ofmovably-connected sections to secure the desired iiexibili ty of theindicator and to enable the arms thereof to yield or bend to the desiredextent.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A device of the class described having an adjustable indicatorprovided between its ends with a hinged joint, the hinged portion beingarranged to swing toward and from a book, whereby the adjustableindicator is adapted to conform closely to the configuration of a bookand to lie against the leaves when the same are rounded or bulged,substantially as described.
